1. The problem statement, all variables and given/known data

Let[tex] 4x^2-4(α-2)xα-2=0 (α\epsilon R)[/tex]

be a quadratic equation, then find the value of α for which both the roots are positive.

2. Relevant equations

3. The attempt at a solution

the conditions will be

1) Discriminant D≥0

by this condition i got α (-∞,2][3,∞)

2) f(0) greater than or equal to 0

by this we get α (2,∞)

3) now should i use -b/2a(point exactly between both roots)

and equate as -b/2a greater than 0

if-3rd point is right then what will be the final answer

α (?,?)union(?,?)

please provide help
